PRESSURE-ACTUATED WINDLASS WITH TACKLE.

Specification of Letters Patent.

Patented June 27, 1916.

Application filed July 15, 1914. Serial No. 851,123.

To all whom it may concern Be it known that I, EUGEN HAGENBUCHER, residing at Essen-on-the Ruhr, Germany, a citizen of the German Empire, have invented certain new and useful Improvement in Pressure-Actuated \Vindlasses with Tackle, of which the following is a specification.

This invention relates to pressure actuated windlass with tackle, using for instance, hydraulic pressure, and its object is to shorten as much as possible the structural length of the Windlass.

One embodiment of the invention is illustrated in the accompanying drawing, where- Figure 1 shows a side view of the windlass; Fig. 2 a plan view of Fig. 1, partly in section; Fig. 3 a transverse section along line 33 of Fig. 2, seen from the right, and Fig. 4: a section along line 11- 1 of Fig. 2, seen from the left. n

The Windlass has a pressure cylinder A, to which pressure fluid is admitted through an aperture c The plunger B is mounted to reciprocate in the cylinder A. The plunger 13 has a head 7) which is guided on two parallel rods C, secured insidewise-projecting arms a on the cylinder A. A foundation plate D, on which the cylinder A is mounted, is provided on each side of the cylinder A, with a bearing E which is intended for holding a trunnion F. These trunnions F are threaded into bosses a of the cylinder A, and serve as journals for pulleys G, H, J. The head 5 of the plunger B moreover carries a gable-shaped bearing K on each of its two opposing sides. On each of these hearings are mounted on journals is two pulleys M, N and O, P respectively.

The pulley rope R, fastened at (Z on the foundation plate D, see Figs. 2 and 3, is led in-the following manner over the guide pulleys. The rope R runs first out from its securing point (Z over pulley N, see particularly Fig. 3, and from there over pulleys H, O, J, M and G to pulley P, and from there to the load. The journals F and 7c of the guide pulleys are arranged so that the axis of revolution of each roller is situated at 90 to the axis of revolution of the next one in line carrying the rope; and that consequently the part of the rope stretched be tween two pulleys lies in the plane of each of those two pulleys. By this arrangement is prevented the formation of forces, which tend to twist the pulleys.

How the Windlass operates on raising or lowering the load, needs no explanation.

I claim:

1. A pressure actuated Windlass having a plurality of guide pulleys for the lifting rope, a working cylinder, a plunger in said cylinder, said pulleys being journaled laterally on said cylinder and said plunger respectively, each pulley being offset 90 to the succeeding one in the train, the axis of revolution of a pulley on one side of the cylinder being parallel with butoffset laterally to the axis of revolution of a pulley on the opposite side of the cylinder.

2. A pressure actuated Windlass having a plurality of guide pulleys for the lifting rope, a working cylinder, a plunger in said cylinder, a cross-head on said plunger, said pulleys being ournaled on said cylinder and said cross-head respectively in such a manner that each pulley is offset 90 to the succeeding one in the train, the axis of revolution of a pulley on one side of the cylinder being parallel with but offset laterally to the axis of revolution of a pulley 011 the opposite side of the cylinder.

3. A pressure actuated Windlass having a plurality of guide pulleys of different diameters for the lifting rope, a working cylinder, a plunger in said cylinder, a cross head on said plunger, said pulleys being journaled on said cylinder and said crosshead in such a manner that the part of the rope stretched between two succeeding pulleys in the train runs parallel to the axis of the working cylinder.

The foregoing specification signed at Barmen, Germany, this 24th day of June, 1914.
